The Polk Audio Reserve R400 is a three-way center channel speaker built to anchor a home theater. It pairs a 1-inch Pinnacle ring radiator tweeter with dual 6.5-inch Turbine midrange drivers and a 6.5-inch woofer, tuned with Polk's X Port to keep dialogue clear and cabinet resonance low. Its 89 dB sensitivity and 4-ohm impedance mean it plays loud on modest amplification, and the 24-inch-wide cabinet fits under most TVs or on a media shelf. Reviewers consistently praise its vocal clarity and wide sweet spot for the money, though some find it large and note it needs a capable amp to shine.
